Generalize Characteristic

[lecoqlibre]

The hasNutrientCharacteristic, hasPhysicalCharacteristic and hasAllergenCharacteristic could be generalized with a Characteristic base class like:

import Measurable from "./Measurable.js"
import QuantitativeValue from "./QuantitativeValue.js"

export default abstract class Characteristic extends QuantitativeValue implements Measurable {

    private quantityDimension: string;

    constructor(quantityUnit: string, quantityValue: number, quantityDimension: string) {
        super(quantityUnit, quantityValue);

        this.quantityDimension = quantityDimension;

        this.registerSemanticProperty("http://static.datafoodconsortium.org/ontologies/DFC_BusinessOntology.owl#hasQuantityDimension", () => this.getQuantityDimension());
    }

    setQuantityDimension(quantityDimension: string): void {
        this.quantityDimension = quantityDimension;
    }

    getQuantityDimension(): string {
        return this.quantityDimension;
    }

}
